Sometimes you feel it's simply time for a new mattress and sometimes, there's an inherent need to get something better. For me, it was the latter. As a side and back sleeper, I started to experience shooting pain in my hips when I was in bed on my side and it was hindering my sleep in a big way. So change it was, and this time, I wanted to see what something at the very top of the range from a dedicated mattress brand could offer. My previous mattress was from a furniture brand, rather than a mattress maker and the quality is worlds apart.

The Simba Hybrid Ultra mattress is the absolute top of the range that Simba offer, from their Hybrid line. The Hybrid line combines foam and spring technology, giving sleepers the best of both worlds when it comes to support. It's a whopping 35cm deep (meaning you need deep fitting sheets) because of the amount of layers packed in, which make it, supposedly, the most comfortable, supportive and tech-packed mattress they sell.

Simba Hybrid Ultra Mattress: is it worth buying?

The short answer is yes. The longer answer is that the Simba Hybrid Ultra mattress comes with a high price tag (from £1,899 for a single) and so it has to be worth that money. For me, it absolutely is and for many reasons. Firstly, the pain I had been experiencing night after night disappeared from night one with this mattress – it was quite remarkable. The mattress is soft and comforting when you first lie on it, but the layers of foam on springs mean that your spine is perfectly aligned at all times during the night, so it offers incredible support. The second gamechanger for me was a big one; I can no longer feel my husband thrashing around next to me as he turns from side to side in the night. In fact, I no longer wake up when he nips out for a midnight wee. The mattress is designed to isolate movement in this way and it truly does, it's magic. There are many reasons to love this mattress but the proof has been in the pudding for me: I am sleeping a lot better and waking up in the night a lot less.

Simba Hybrid Ultra Mattress: how does it compare one year later?

A year into my love affair with my Simba Hybrid Ultra mattress and I have to confess, my love of it has not waned in the slightest. It has been the best investment in my sleep and continues to be as supportive as it was brand new. The brand advise that you rotate it every few months to ensure you have continual support and, having just done that, it feels brand new again. I'm now pregnant (a condition which throws all manners of discomfort and insomnia your way) and am finding I have no discomfort at all in bed this time around, given how good the mattress is. The other thing I really appreciate about it is its depth as I love a super high bed and I (a tall person) have to clamber in and out of bed, which feels oddly luxurious. It's held up brilliantly and I love it all the more.
